MOBILE, Alabama -- During a press conference in downtown Mobile today, Gov. Robert Bentley said that the mandatory evacuation orders for parts of Mobile and Baldwin counties could be adjustments in the next few hours in preparation for the effects of Tropical Storm Isaac, and that he will determine that when he and his team arrive in Montgomery later today.

The adjustments could come in Zone 2 in Baldwin County, and Zone 1 in Mobile County, Bentley said.

For now, the evacuation orders that went into effect at 8 a.m. today stand for residents of flood-prone areas in south Mobile and Baldwin counties.

"We'll do whatever we can to help those people out," Bentley said during the press conference. He said he had already spoken with Florida Gov. Rick Scott about storm preparations, and expects to speak with the governors of Mississippi and Louisiana later today, as well as Homeland Security Director Janet Napolitano.

He is scheduled to speak with President Obama about preparedness at 2 p.m., he said.

"We're trying to protect the lives of the people of this area," Bentley said from the Mobile Convention Center. "Everything else is secondary."

Jeff Garmin, with the National Weather Service in Mobile said that the latest information it's collected indicates that Isaac has a "fairly large" wind field, and that tropical storm-force winds, between 39 and 73 miles per hour, extend 100 to 200 miles away from the center of the storm.

According to the NWS, as of noon today, Isaac was about 300 miles south of the mouth of the Mississippi River and is expected to become a hurricane before reaching the northern Gulf Coast late Tuesday.

"I know folks tend to really want to focus on where the black dot is on the hurricane tracking map, but you really can't do that with this system," Garmin said.

The eye of Isaac is currently on track to move over southeast Louisiana sometime Tuesday, but he cautioned that "the average track error, two days into the future with a tropical cyclone, is about 80 to 100 miles."

For south Alabama residents, Gov. Bentley's evacuation order continues to include Zones 1 and 2 in the two coastal counties. Those areas are defined as:

In Baldwin County: Zones 1 and 2 include all areas south of U.S. Highway 98 and areas on the Eastern Shore of Mobile Bay that are South of Interstate 10 and west of U.S. Highway 98. Additionally, all people living in proximity to the Fish, Styx, Blackwater, and Perdido Rivers should evacuate. Also, all people living in manufactured homes, and those living in low-lying, flood-prone areas should evacuate.

In Mobile County: Zones 1 and 2 include areas south of Interstate 10 and those areas that are north of I-10 and east of I-65 and east of U.S. 43. Also, all people living in manufactured homes, and those living in low-lying, flood-prone areas should evacuate.
